Currently, `boinc-manager` package (as��of��version 7.2.42-3.2) provides these
program files:

��� /usr/bin/boinc-gui ��� GUI Manager binary, called `boincmgr` in��upstream;
��� /usr/bin/boinc-manager ��� wrapper script for��running `boinc-gui`;
��� /usr/bin/boincmanager ��� symlink to��`boinc-manager`;
��� /usr/bin/boincmgr ��� symlink to `boinc-manager`.

All what `boinc-manager` script does is to��ensure that authentication secret
file ~/gui_rpc_auth.cfg exists (defaulting to��be a��symlink to
/var/lib/boinc/gui_rpc_auth.cfg) and��then just launches `boinc-gui -e
/usr/bin`.

Theoretically, option `-e` has the��following meaning:

> -e, --clientdir=<str>   Directory containing the BOINC Client executable
> -d, --datadir=<str>     BOINC data directory

However, it appears to��specify the��location of��manager's data/root directory,
including gui_rpc_auth.cfg, as��seen in��source code (clientgui/BOINCGUIApp.cpp):

> if (!parser.Found(wxT("clientdir"), &m_strBOINCMGRRootDirectory)) {
>     m_strBOINCMGRRootDirectory = ::wxGetCwd();
> }
> if (!parser.Found(wxT("datadir"), &m_strBOINCMGRDataDirectory)) {
      m_strBOINCMGRDataDirectory = m_strBOINCMGRRootDirectory;
> }

There is probably some `chdir()` involved, because gui_rpc_auth.cfg is then
read from��current directory (clientgui/MainDocument.cpp):

> int CNetworkConnection::GetLocalPassword(wxString& strPassword){
>    // .....
>    FILE* f = fopen("gui_rpc_auth.cfg", "r");
>    // .....
> }

Consequently, with��`-e /usr/bin` specified, gui_rpc_auth.cfg is searched in
/usr/bin, which results in��inability to��communicate with��`boinc-client`, as
observed in��issues like #788297. When run from��user's home directory without
arguments, `boinc-gui` successfully connects to��backend, as��well as��when run
with��`-e $HOME` or��`-d $HOME`.

Proposed solution is therefore to��alter (openSUSE-provided?)
/usr/bin/boinc-manager script by��changing

> exec boinc-gui -e /usr/bin

to��either

> exec boinc-gui -e $HOME

or

> exec boinc-gui -d $HOME

or

> cd ~
> exec boinc-gui

It would also be nice to��update
/usr/share/doc/packages/boinc-client/README.SUSE by��removing questionable
advices for��working around this issue by��disabling authentication or��entering
password each time.
